Question

A cyclist cycles north at a rate of 20m/s and then speeds up to 30m/s after 10 seconds. What is the

acceleration?
a. 600 m/s north.
c. 1 m/s/s north.

Answer 1

To find the acceleration of the cyclist, we can use the formula:

Acceleration (a) = (Final Velocity (v) - Initial Velocity (u)) / Time (t)

Given:
Initial velocity (u) = 20 m/s (cycling north)
Final velocity (v) = 30 m/s (after 10 seconds)
Time (t) = 10 seconds

Substituting the values into the formula:

Acceleration (a) = (30 m/s - 20 m/s) / 10 s

Simplifying the calculation:

Acceleration (a) = 10 m/s / 10 s

Acceleration (a) = 1 m/s²

Therefore, the acceleration of the cyclist is 1 m/s² north.
